Answer:
The answer is the VPg Protein.
Explanation:
The question is incomplete, here is the full question:
Poliovirus is a positive-sense RNA virus of the picornavirus group. At its 5' end, the RNA genome has a viral protein (VPg) instead of a 5' cap. This is followed by a nontranslated leader sequence, and then a single long protein coding region (~7,000 nucleotides), followed by a poly-A tail. Observations were made that used radioactive amino acid analogues. Short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides.
What part of the poliovirus would first interact with host cell ribosomes to mediate translation?
A) the poly-A tail
B) the leader sequence
C) the VPg protein
The part of the host cell ribosome that the poliovirus would interact first is the VPg protein because the poliovirus has to affect the RNA to be able to replicate it's own DNA and the VPg protein is attached to the RNA's 5' end.

Answer:
Cell copies its genetic material during the S-phase of the interphase during cell cycle.
Explanation:
- Cell cycle is broadly divided into two phases ; the interphase and the M-phase.
- M-phase is the dividing phase during which the karyokinesis and cytokinesis takes place.
- Interphase is the phase during which the cell prepares itself for division.
- It is further divided into G1, S and G2 phase.
- During G1 phase the cell prepares for DNA replication and the replication complexes assemble.
- The next phase is S-phase during which the DNA replicates itself and the genetic material in the cell doubles.
- The Next phase is G2 phase during which the DNA is scanned by DNA tepair complexes and errors in the replicated DNA are edited and repaired.
- At the end of G2 phase the cell prepares to enter M-phase.

Question
<em>Define enzyme concentration.</em>
Answer:
<em>Substrate concentration is the amount of substrate present that can be turned into product and is most commonly measured in molarity (moles per liter). The concentration of substrates is often used to measure enzyme activity, which is based on the rate of a reaction (product formed over time).</em>

An example of Nuclear Fusion happening naturally, is the core of the Sun. The core of our Sun is 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms are constantly being compressed and fused together to create helium through Nuclear Fusion.
